诸子百家：

墨家的“素丝说”说明了环境对人的发展起主要作用。

答案

参考答案：这种说法是正确的。
墨子以素丝和染丝为喻，来说明人性及其在教育下的改变和形成。“染于苍则苍，染于黄则黄，所人者变，其色亦变。”在他看来，人性不是先天形成的，生来的人性如同待染的素丝，下什么染缸，就成什么颜色的丝，有什么样的环境就造就什么样的人。因此必须慎其染，他从人性平等立场出发去阐述教育作用，较之孔子的人性论在社会意义上更进一步。但很明显这是一种“外发论”，强调环境的重要作用，没有认识到人的主观能动性，具有一定的片面性。

请以Tom的身份给Jenny写一封回信，描述你自己的房间，文字不少于50词。

Hello,

    This is a picture of my room. There's a bed, of course, and there are two pictures of movie stars above

the bed.

    There's a bookcase next to the bed. There are lots of books on it. There is a radio under the bookcase,

and there are also some CDs.

     There is a dresser in the other corner. There is a table and a chair under the window, between the dresser

and the bookcase. I do my homework and write letters, too. There is a computer on the table. There is a

lamp on the table, too.

     The room is not perfect. There isn't a TV and there isn't a telephone! Tell me about your room. Is it big?

                                                                                                                                                  Love, 

                                                                                                                                                  Jenny

问答题

某水库枢纽工程由大坝及泄水闸等组成。大坝为壤土均质坝，最大坝高15.5m，坝长1135m。该大坝施工承包商首先根据设计要求就近选择某一料场，该料场土料粘粒含量较高，含水量较适中。在施工过程中，料场土料含水量因天气等各种原因发生变化，比施工最优含水量偏高，承包商及时地采取了一些措施，使其满足上坝要求。坝面作业共安排了A、B、C三个工作班组进行填筑碾压施工。在统计一个分部工程质量检测结果时，发现在90个检测点中，有7个点不合格。其中检测A班组30个点，有2个不合格点；检测B班组30个点，有3个不合格点；检测C班组30个点，有2个不合格点。
